Ana Ivanovic celebrated her 24th birthday by successfully defending her Tournament of Champions title with a comfortable 6-3 6-0 victory over Spain's Anabel Medina Garrigues on Sunday.
The victory was the Serb's 11th singles title but first since winning the event last year. Her previous best results in 2011 were achieved with semi-final appearances in Birmingham and Carlsbad.
The Spaniard was seeking her third title of the season following victories in Estoril and Palermo, and had enjoyed an easier route to the final after her previous two opponents this week retired from their matches.
Marion Bartoli suffered an ankle injury and quit after holding two match points and Sabine Lisicki failed to complete the third set of their semi-final due to a back problem.
